Five guides for the moments when a document is too sensitive to hand to a server.
Most online PDF tools upload your file to a server
What actually happens when you drop a PDF into a web tool, what "we delete it after an hour" really means, and a 10-second test to see for yourself.
Read the guide RedactionRedact a PDF without uploading it to any server
Do the redaction on your own device, so the file never leaves it. That closes two risks at once, with a SHA-256 record that proves the text is actually gone.

The thread through every guide: the work happens on your device, not on ours.
Load the page, then turn on Airplane Mode and run any tool. It still works, because your file was never going anywhere in the first place.
With the network on, you will see small first-party pings for the daily quota and our analytics, never your file, and no third-party trackers. That is the honest version of "private": the document itself is never part of a single request.
